Embodiment 1
[0053] A battery charging method such as figure 1 shown, including the following steps:
[0054] S1: The system is powered on and reads the SOC value in the computer storage medium to perform the charging state;
[0055] S2: Divide the SOC value into an interval including a low battery SOC interval and a high battery SOC interval;
[0056] S3: Read the interval where the SOC value is located, and determine whether the SOC value is in the low SOC interval of the battery. If so, use low-current constant-current charging, otherwise, execute S4;
[0057] S4: Determine whether the SOC value enters the high SOC range of the battery, if not, use high-rate constant current charging, otherwise execute S5;
[0059]S6: Determine whether the pulse current is greater than the minimum current, if so, use the pulse current to charge, otherwise use the minimum current to charge.
Embodiment 2
[0061] like Figure 2-6 As shown, a battery charging method includes the following steps:
[0062] S1: The system is powered on and reads the SOC value in the computer storage medium for charging status.
[0063] Among them, S1 specifically includes the following steps:
[0065] S12: Read the SOC value in the computer storage medium;
[0066] S13: Continue to judge whether it is in a charging state, if so, go to S14, if not, return to S12;
[0067] S14: Divide the SOC value interval into a battery SOC low interval and a battery SOC high interval.
[0068] S2: Divide the SOC value into an interval including a low battery SOC interval and a high battery SOC interval;
[0069] The low range of SOC is battery SOC<10%;
[0070] The range of the high battery SOC range is battery SOC>90%.
[0071] S3: Read the interval where the SOC value is located, and determine whether the SOC value is in the low SOC interval of the battery, if so, us...

Abstract
The invention discloses a battery charging method and a computer-readable storage medium, which overcome the problems of long charging time and overcharging prevention function in the prior art. value to determine the charging method used, including low current charging, high rateconstant current charging, and when the remaining battery power is in the high SOC range, the pulse current is judged to choose between the two charging methods of minimum current and pulse current. Reduce the charging polarization voltage of the battery cell, adopt the equivalent exponential curve of the stepped rectangular group to reduce the output difficulty of the charger, and at the same time ensure that the charging is performed at the maximum close to the maximum charging current, reducing the charging time and achieving the purpose of fast charging.
Description
technical field [0001] The present invention relates to the technical field of battery management, and in particular, to a battery charging method and a computer-readable storage medium that reduce charging time and damage to the battery. Background technique [0002] As the market has higher and higher requirements for new energy vehicles, energy storage, and 3C electronic products, the battery charging speed has attracted much attention. A suitable charging method can reduce the charging time, prevent the battery from being overcharged, and reduce the damage to the battery caused by charging. [0003] At this stage, the main charging method is CC (Constant Current, constant current)-CV (Constant Voltage, constant voltage) charging method. When the remaining battery power is in the low range, CC charging is used. By increasing the charging current, the charging time is shortened. When the remaining battery power reaches the high range, the CV method is used to charge, and ...
